TOYLZZ whom/t may concern.'

Beit known that I, THOMAS W: DEMA- Rnsr, a jcitizen of the UnitedStates, and a `:resident of Pittsburgh, inthe county ofAl- "legheny andState of Pennsylvania, have inlvented certain newqand usefulImprovements in Journal-Box` Lubricators, of which the following is aspecification.

My invention relates in general to lubricaters;` and more particularlyto pressure lubricators, andglias special reference to the provision ofan improved type of lubricator adapted for theautomatic feeding ofthe"lubricant tovdriving box journals or railway locomotives 1n order toinsure the pressure of a `continuous ilmof grease between thejbearingsurfaces of the axle` and journal* bearing restinguponrit andthereby, as far "as possible,` minimize the occurrence of a j tolocomotive drivinigbox journalsand that i i general typeinwhich mypresent invention hot-box andthe `frequent stoppages and interferencesincidental thereto, and whereby not only maythe life of thejournal brassi be greatly increased but the locomotive may be kept on the road foralonger period of timewithout lay-up in the shoporreplacementoflthejournal 'brass7 thus avoiding both 1theeXpense of newmaterial and of labor incident to placing it in position, and

` also loss of the use-of the locomotive. 30

`designed particularly for feeding" hard Lubricators of thel` typereferred to are greasein cake "form, rather than iuid oils,

finds perhaps its. greatest field of utility includes 1 a perforated Ior foraminous plate which bears marginally against-the journal of thedrivingbox andsiis adapted to distrib- 1 bute `the grease andregulatethe feed thereof to the axle; a follower-plate or riser, which supportsthe grease cake, and a spring actingpn the follower-plate or riser tokeep the grease cakevin contact with the perforated plate,Y `allcontainedlwithin a` casing or cellarb Means are providedby me forpulling `down .the: follower-plate and distributer plate, whether forinspection of the condition of the lubricator or for replacey greasecake or parts worn away in Service.1

The principal i. objects of `my present invention` are` `gentn'ally lto`improve, sim lify, andycheapen the cost of producing ubricaters1 oftheacharacter referred to; to `ren-` ider such i lubricators lesscomplicated in structure and more eilicientin operation, and

less expensive in manufacture and in the cost of maintenance; theprovision ofthe sitionin order to permit the insertion of a fresh cakeand which is below such plate whenthe latter is in its upper position inwhich the cake is brought into action on the feedor distributer plate;the provision of a spring` supporting device acting on the riser-plateat `a number of points. so that the plate.` is not 4only supported onthe bottombut `also is guided on its sides whereby any `tendency towardcocking and consequent cramping` in the casing is avoided; vtheprovision of a bottomless container-cellar having continuousV sides andends adapted to contain the grease-cake and prevent on the lone hand anylateral exudation there- Vof with consequent loss and on the other handthe entrance of any foreign matter; `the provision of a riser-plateprovided with raised longitudinal sides of sufficient depth to containthe grease-cake in such a maulner as to prevent any seepage or loss of`grease from the riser-plate except through a fresh cake of grease; theprovision of a container-cellar provided with continuous ends and sidesof sufficient depth, in combination with a feed-plate and riser-plate,to

contain and cover the grease-cake on all sides while the lubricatordevice is in operative position; together with such other objects as mayhereinafter appear.

In attaining the objects referred to, togfether` with `such additionalbenefits and advantages asmay bevbelow pointednout,

Patented N0v.15,'1921.

embodying my present improvements ;l

Fig. 2 is a longitudinalsectional elevational view thereof taken on theline 2-2 of Fig. l;

Fig. 3 Vis a transverse sectional elevational view thereof taken on theline 3.-3 of Fig.k

1; and

p AF ig. 4 is a perspective view of a conventionalform of grease-cake,inserted in the device inthe first instance.

On referring to the drawings, it will be observed that I have indicateda'topless and bottomless cellar 10 provided with continuous ends andsides, 11 and'12., the ends 11 being marginally curved, as. 1sY perhapsmost clearly to be seen `on viewing Fig. 3, to

, conform to the contour of the axle 13.

Within the cellar is arranged a foraminous grease feed ordistributenplate 14, having a number of perforations 15, the plate 14being also curved, as clearly to be seen on inspectionof Fig. 3, toconform to the contour of the axle 13.

With the cellar 10 and surrounding the feed-plate 14 is a follower-plateor riser 16 which carries the grease-cake. This riser 16 has upturnedsides 17 provided with inwardly turned marginal portions 18 adapted tokcontact with shoulders 19 formed on the downwardly turned sides 20aofthe feedplate 14, as clearly to be seen on viewing the dotted portion ofFig. 3, in order that downward movement of the riser 16 may carryV alongthe distributer 14.

' `*For sustaining the riser or follower-plate 16, which carries thegrease-cake 31, and for pressing it upward in order to force thegrease-cake against the feed-plate 14 and thereby press the grease, asit becomes warmed, through the apertures 15 in the plate 14.V and soafford a continuous feed of grease to the axle 13, I employ a number ofcoiled spring devices 20, each of which is of a generally invertedU-form (see Fig` 3) Y and is vprovided at each end with a number ofcoils 21V which are disposed in retaining sockets 22-formed in the walls12 of the cellar 10.

The ends 23 of the springs are inserted in openings in the sides 12 ofthe cellar in order to keep the springs under compression and therebyinsure that the riser 16 is caused .4 to approach the feed-plate 14, asclosely as the body of the interposed permit. l 1

In order to afford; full support for the follower 16 at bothen'dsthereof, the legs grease-cake will g 24 of the spring device 20 are bentlaterally and may be .conveniently made integrally so as to continue they'support of the riser or follower entirely across its endsas indicatedat 25 (see Fig. 1) and afford a fourpoint support thereto, and preventcanting.

As further means for preventing any canting of the riser or follower 16,brackets A 26 26 are amlied to the under side of the riser or follower16 and so arranged that the portions 25 of the spring device shall atall times be confined to movement within the length of such brackets.

For retracting the follower 16 from within the cellar 10, that iswithdrawing it therefrom and into the position at dotted lines in Fig.3, for replacement of the grease-cake, a number of depending legs 27(see Fig. 2) apertured as indicated at 2S for the reception of hooks,(not shown), are conveniently employed.

Inasmuch as the retraction of the riser 16 eventually carries along withit the feedplate 14, owing to the contact of the marginal extensions 1Swith the shoulders 19, above referred to, it will be perceived thatthe.distributer-plate 14 may be readily removed at any time for cleaningor replacement.

From inspection of Fig. 3, it will also be apparent that theconstruction described permits the retraction of the riser or follower16 to a point suiiiciently far below the lower margin 29 of the cellar10 to permit the insertion of a fresh grease-cake between the lowermostpoint 30 of the feedplate 14 and said riser 16, without any interferenceby the outer end 11 of the cellar 10.

As will be understood on viewing Fig. 3, care should be used inassembling the device in order to keep the spring coils 21 well withinthe sockets 22 so that such coils may not interfere with either theupward or downward movement of the riser 16.

TWhile I have shown in full lines in Fig. 4 a conventional form ofgrease-cake, 31, to be inserted in the device in assemblingV it in thefirst instance, it will be understood that the cakes of greasesubsequently inserted from time to time in replenishing the supply areof rectangular cross-section as indicated in dotted lines in such Fig.4.

Having thus described my invention and illustrated its use, what I claimas new and desire to secure by Letters Patent is` 1. A lubricatingdevice comprising, in combination with a casing, of a distributer, alubricant-supporting follower or riser, and a spring device arranged insaid casing outside of the path of movement of said distributer andriser, and adapted to cause said riser to approach said distributer, thebody of the spring device being below the riser when the riser is in itsuppermost position, and above the riser when the riser is in itslowermost position.

a spring device in said casing for causing said riser to approach saiddistributer, the spring device being so constructed and arranged in thecasing as to permit the riser to pass it in either direction withoutinterference with its movement.

3. A lubricating device comprising, the

combination with a casing, of a distributer,

a lubricant-supporting follower or riser and spring means acting inopposition to each other on both ends of said riser and adapted to causeit to approach said distributer.

4. A lubricating device comprising, the

combination with a casing, of a distributer,

a lubricant-supporting follower or riser, and spring means acting 1nopposition to each other on opposite portions of said riser and closedsides and ends and an open bottom distributer w all so arranged thatsaid riser may be withdrawn throughthe open bottom of the casing for theinsertion of a fresh supply of lubricant upon the top of said riser.

47. A lubricating device comprising, the combination with a casing, of adistributer, a lubricant-supporting followerfor riser, and a springdevice arranged in said casing for causing said riser to approach saiddistributer, and means for limiting the maximum distance of separationbetween said riser and distributer, the said riser having upwardly7extending longitudinally arranged sides of a height greater than themaximum distance of se aration between said riser and iiereby lateraldisplacement of the lubricant carried by the riser is prevented. i

8. A lubricating device comprising, the combination with a casing, of adistributer, a lubricant-supporting follower or riser, and a springdevice arranged in said casing adapted to cause said riser to approachsaid distributer, said riser and distributer being provided with meansfor inter-engagement whereby7 the distributer may be retracted when theriser is retracted from said casing.
